An Edge to Edge Comparison

Compare fineblanking to other technologies such as conventional stamping, machining or powdered metal and find out how Burkland Inc. will give you a competitive edge.

Fineblanking vs. Conventional Stamping

The conventional stamping process can generate an initial cost advantage, but these savings are quickly lost when secondary operations are needed to achieve flatness, edge precision, exacting size features and consistency. Fineblanking can produce products with functional edges, extreme flatness, minimum die-roll and a variety of features through operations such as piercing, semipiercing and coining--all in a single press cycle. In thicker materials (in excess of .375 inches), cupping and edge tearing, both common in heavy stampings, are virtually eliminated. Fineblanking, when compared to conventional stamping, is the superior technology for the production of metal parts where precision and cost are design considerations.

Fineblanking vs. Machining

Machining processes can produce precision products, but typically at slower speeds and at a cost greater than their fineblanked replacements. Additionally, fineblanked profiles are coldformed rather than cut. This allows the metal’s grain to follow the contours of the part uninterrupted. Cutting through the metal’s grain can create potential fatigue points. Fineblanking, as an alternative to machining, can offer parts with identical precision, greater resistance to fatigue, and often significantly lower costs.

Fineblanking vs. Powdered Metal

Intricate forms can be produced with the powdered metal process, but design strength can only be increased by increasing the mass of the part. Even then, powdered metal’s strength is still found mainly in compression. Fineblanking, which utilizes a variety of metals and alloys, can offer torsion, tension, shear and compression strength while significantly reducing the part’s mass-to-strength ratio. When specified in place of powdered, fineblanking can offer material advantages in both product integrity, conservation of material and component strength.

The Material AdvantEdge

Fineblanking offers you all the primary advantages of stamping, machining and powdered metal without any of their inherent technical shortfalls. Whether your application calls for one or a combination of material advantages--low cost, dimensional precision, functional edges, high perpendicularity, superior strength, extreme flatness and complex shapes and profiles--you can count on Burkland Inc. to deliver the edge…the Material AdvantEdge.
